If this was on private property, which it appears to be, then no laws have been broken as to the doing donuts. As for the deputy, yes, it sets a bad example, but it looks like he was just blowing off stress and taking a minute to have fun with the citizens of NHC while on private property. I'd just make this deputy pay a percentage of the cost to replace the tires when they need replacing. I don't think this needs to be blown all out of proportion here. He just done a burn-out in a empty parking lot and had a moment of fun.
